What’s on this acro?

There’s at least two, is this just how they grow?

I think that is an imbedded filter feeder ? Barnacle

There’s also two small crabs in there I cant get a picture of. Kind of a burnt orange colour, do they sound reef safe?

If they are flat and hairless, then they are safe and actually beneficial Trapezia crabs. If they are thick and hairy then they are probably Cymo crabs, which often nibble on the corals they live in. The Trapezia will die out in the open, however if they are Cymo then you can toss them in the sump and let them live there.

Is that a wild acro? The hitchhiker crabs are often good for keeping the algae off the base of the coral. Check out what was just posted and act accordingly

they’re flat and hairless but no spots like on google. That’s great though, thanks!

only some species have spots, the ones that inhabit Acropora tend to be spotless. You've hit the jackpot! Not only will the craps feed the coral with their poop, but they can also help keep populations of redbugs and flatworms to a minimum.
